In his early years, Mr. Du also watched the description of the scenery of various places from travelogues, miscellaneous notes, and strange novels, and also sketched the scene of the sunset over the long river, and gave new words with the sigh and thought in his heart, and waited until he really arrived in the Northwest Army, only to understand what it means to be covered with yellow sand and strange rocks, and to truly understand the drought and terrain of the Northwest, but the description and drawing in this book are based on the Northwest and never detached from reality, how did this person come up with it for no reason, Li's house was raided, and Li Rui's every move from the cell was monitored, He had not looked for any relics of his ancestors at all, and this book must have been written by him himself, so this person was too ...... Mr. Du couldn't think about it anymore, he fell into a dead end like King An, and couldn't figure out why Li Ruixiu didn't choose to support the family back then, but now he is sending people under the fence, is it really just for cultivating immortals and preaching?

Mr. Du flipped through the formation map again, and it was obvious that the formation was combined with the terrain of the northwest, and it was very closely combined, and from his knowledge, if there was really a cannon as written in the book to cooperate, maybe he could bombard the cavalry at least four cannons in front of the formation, then no matter who the cavalry was, they would have to be defeated. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info He was a little excited to hold the book, but he was not in a hurry to give it to King An, the Inner Government Supervision Bureau did not have this kind of artillery, the whole set of books was talking about soldiers on paper, talking about soldiers without weapons, he packed up his things, prepared to pay tribute, and was ready to come to the door in person to ask Li Ruixiu about this artillery, Mr. Du secretly expected that Li Ruixiu did not provide artillery just because he wanted to wait for the price and sold it, rather than imagining that the Chinese army had such a beneficial artillery waiting for him to fiddle with at will.

Li Rui corrected the drawings of the Furlong cannon at home, copying the parameters of each part, because the book had been copied to the Chinese army, he was not in a hurry at all, while copying, while tasting the scientificity of the design, watching all kinds of circumference, differential, and pressure formulas being perfectly reflected in this design drawing, he danced happily, took a pen and wrote a paragraph of formula graphics on the white paper on the wall, these formula graphics are like the formula board that only the old professor of the fairy world can have, whenever he sees the formula filling the paper, He was a little excited and carried away.

Mr. Du came to visit at this time, Li Ruixiu frowned a little displeased, blindfolded and went to the main house to invite someone in, Mr. Du arched his hand and said: "Du Mou saw the great work of the art of war of the horse very admired, the four manuscripts, the road is exhausted, as if you have studied in the army for many years, you can guide the frontier war without leaving home, it is really the reincarnation of Sun Wu." ”

Li Ruixiu heard Mr. Du's uncontrollable praise, a little blushing and then a little displeased, he is busy studying here, you have the military book, why bother to come over to praise, there is this gap, it is better to urge the glaze factory and the internal affairs government to hurry up the time to make their own copper wire. Of course, Li Ruixiu knew in his heart that this Mr. Du was not such a boring person, and after praising him, it was time to introduce the topic, could it be that he wanted to urge himself to train craftsmen to learn to detect ores as soon as possible?

Li Ruixiu was a little angry at the moment, he kept sleepless for the Chinese army to copy a set of formations that were useless to themselves and destined to be eliminated by firearms, they were not satisfied, and they kept running over to urge themselves to teach experiments to those craftsmen, he was really insatiable, he said in a displeased tone: "Mr. is here, there must be something important, you might as well get to the point, Li still has many experiments to do, and many immortal arts have not been learned." ”

Mr. Du was pushed by Li Ruixiu, a little inexplicable, but Li Ruixiu has always had a strange temper, and even dared to rob the court officials in the prison of the Criminal Department, and his tone was normal at this time, he said: "Then Du is abrupt, the "Che Battalion Buckle and Answer Compilation" written by the horse, the chariot soldiers, infantry, and cavalry are well coordinated, and the offensive and defensive marches are described in detail, but its core is written around a kind of artillery that weighs only 1,000 catties. ”

Li Ruixiu was stunned for a moment, and then suddenly found that he didn't send the Furlong machine to the bottom of the mountain, and he was still copying it in his study, he hurriedly gave it up: "It was Li's mistake, I forgot to send it to the fire*** Mr. Sit for a while, the Furlong machine gun has been designed, and I will sort it out." ”

Mr. Du saw Li Ruixiu go to get it in person, and thanked him repeatedly, although he had doubts in his heart, but thinking of Li Ruixiu's various designs, converters, military thorns and camouflage, all of them were artifacts that he couldn't think of, he settled down again, and soon Li Ruixiu came out, Mr. Du took the design with both hands, and looked at it on the spot, the content was detailed, the data was perfect, and it looked like it could really be made, and there was also a method of using this cannon at the back, calibration, loading, repair, etc., as if this cannon had been used countless times, He hurriedly said goodbye to Li Ruixiu, returned to the Chinese army with the drawings, and took the "Cheying Deduction and Answer Compilation" to meet King An.

King An got the books and materials, and he was naturally surprised when he looked through them, he thought that Li Ruixiu would make better armor and stumbling horses, but he didn't expect that Li Ruixiu would take out a new cannon in just a few days, and also compile a formation information based on this cannon.

Looking at the design of this artillery, this kind of Furlong cannon has 5 sub-guns, each of which is filled with elixir, and is put into the mother gun in turn to fire, so that the speed is greatly improved, the disadvantage of the gun is that it is heavy, and the other is that the gunpowder is filled and the shells are very slow, and the second shortcoming is completely overcome with this design, the design of this gun is short and light, and the firing range is only more than 100 zhang, but it is enough to disperse the impact of a cavalry, so it is necessary to have infantry to protect this cannon, and there must be a baggage force to escort gunpowder.

Wang An looked at this artillery in amazement, and imagined in his mind how to integrate this new type of artillery into his army, and where to put it to play the greatest role, he did not doubt whether the things made by Li Ruixiu could be realized, since it was written here that they could fire a hundred zhang, and the things would definitely be able to be made, he didn't realize that he unconsciously began to trust Li Lufeng's grandson.

Summoned craftsmen, ripped drawings, opened molds and made cannons, King An was ready to test the power of this cannon on Suoyan Mountain first, and arranged these things, he began to look at the military book written by Li Ruixiu, he trusted Li Ruixiu very much, but he sneered at the military book written by Li Ruixiu, during the heyday of the Li family, the top and bottom wanted to occupy a place in the army, but those children were pedantic and dogmatic, and they didn't know how to adapt to the situation when marching and fighting, and they didn't understand the deception and slackness of those soldiers in the army. will only find examples from books to reason with people, and be bullied by all kinds of people in the barracks openly and secretly, and now this Li Ruixiu will write military books while sitting at home?
